Beit known that I, FRANKLIN D, TIFF, of Beaver Falls, in the county ofLewis, in the State of New York, have invented new and usefulImprovements in Apparatus for Shaping lVood and Pulp Plates, of whichthe following, taken in connection with the accompanying drawings, isafull, clear, and exact description.

Ic This invention relates to the class of apparatus which are providedwith a steamheated cylinder containing the dies between which are placedthe blanks to be pressed into shape by the power of a screw applied tothe die in one end of the cylinder.

The invention consists in an improved construction and combination ofparts constituting an apparatus which is simple and comparativelyinexpensive in construction and 2c most convenient and etlicient in itsoperation.

In the annexed drawings, Figure lis partly a top plan view and partly alongitudinal section of an apparatus embodying my invention. Fig. 2 is afront end View of the same.

Fig. 3 is a vertical transverse section on line X X in Fig. l, viewedtoward the adjacent end of the cylinder; and Fig. 4 is a detachedperspective view of the rack which supports the blanks in the cylinder,portions being 3o broken away to illustrate the detail construction ofsaid rack.

Similar letters of reference indicate correspending parts.

O represents the metallic cylinder in which the blanks are to betreated. This cylinder is formed with a steam-jacket D to heat theblanks during the process of pressing them into shape. The steam isadmitted into said jacket by a steam pipe or pipes a, connected 4o toone end thereoiand a drip-pipe (not shown) is connected to the base ofthe opposite end of the jacket for the escape of the water ofcondensation. The jacket D is of segmental shape in cross-section toform in the upper portion of the cylinder the openingD',through which tointroduce the blanks into the cylinder and remove them therefrom afterthe blanks have been pressed into the requisite dish shape.

5o A suitable door B, hinged to the jacket, as

at b, orotherwise removably connected thereto, closes the opening D'during the process of shaping the blanks. R denotes a rack which isemployed for supporting the blanks within the cylinder. The aforesaidopening 5 5 D' is of sufficient size to allow said rack to pass sidewisethroughit. In order to effectually expose the blanks to the heat in thecyl in der O, I make said rack of the form of a skeleton frame,consisting of cradles c c, of ap- 6o proximately semicircular shape andformed with eyes d d d, through which pass rods d', provided with nutson their ends. The cra dles are confined at their requisite distancesapart by means of metallic pipes, preferably sections ff of pipeabutting against the cradles and receiving the aforesaid rods throughthem. To brace and properly sustain said cradles in the cylinder, I formthe cradles with feet c c, by which they rest on the inte- 7o rior ofthe cylinder, as shown in Fi g. 3 of the drawings. Y

g and g represent, respectively, male and female dies for shaping theblanks placed between them, as illustrated in Fig. l of the drawings.One of the dies, preferably the female die g', is seated in a recess a"in the inner face of the adjacent head h' of the cyl inder and isretained therein by a bolt u, passing through the head and entering ascrew- So threaded socket in the back of the die. The other die, g, isformed with a hub j in the cen ter of its outer face, and this hub isformed with a socket in which the end of the pressscrew I is pivotallysecured by means of a 8 5 screw r, passing through the side of the huband entering a circumferential groove in the screw.

The cylinder O rests horizontally on stout saddles S S,whicl1 aresecured to cross-beams 9o F F, mounted on longitudinal sills G G. Thetwo heads h and 7L of the cylinder O are tied to each other and to thecylinder by means of stout longitudinal rods i172, passing through andfastened bynuts t" and collars Htc cross- 9 5 bars L L, extending acrossthe sections of the cylinder-heads h h. The tie-rods il i extend beyondthe end of the cylinder through which the screw I protrudes, and to saidextensions are fastened the two cross-heads N N, whichl are provided intheir centers with openings through which the screw I passes. BetweenIOO beams F', fastened to the sills G G.

the said cross-heads is sustained the hub O of the gear-wheel O. Saidhub has its axial orifice screwthreaded and constitutes the nut of thescrew I, which passes through it. A shaft l, parallel with said screw,is mounted in suitable bearings Z Z', secured to cross- To this shaftare fastened a driving-pulley n and a pinion Rwhich latter meshes withthe aforesaid gear-wheel O. A belt (not shown) connects the pulley nwith a suitable motor and transmits rotary motion to the ,shaft Z. Theengagement of the pinion P on said shaft with the gear-wheel O causesthe latter to partake rotary motion. The hub of said wheel serving as anut for the screw I causes the latter to travel longitudinally. Bychanging the direction of the motion of the drivingbelt the Screw ismade to travel toward and from the cylinder C.

In an extensive apparatus having a cylinder C of considerable length Iemploy intermediate dies 't interposed at intervals between portions ofthe row of blanks, as illustrated in Fig. l of the drawings.

The operation of the designed apparatus is as follows: The screw Ihaving been retracted to carry the die g to one end of the cylinder C,the door B is opened and the blanks of wood or pulp are introducedthrough the opening D' and placed contiguously side by side in a row andendwise into the rack R, and, if necessary, the intermediate dies t tare inserted at the same time. After the blanks and said dies have beenproperly adjusted the door B is closed and the steam turned on to chargethe jacket D and thereby heat the cylinder C. The blanks in saidcylinder are thereby rendered more elastic to yield to the subsequentshaping process without splitting. The screw I is then set in motion tocompress the row of blanks between the dies and thereby impart thedesired dish shape to the blanks. After the blanks have been held insaid condition for a sufficient time to render the shape permanent theaforesaid operation is reversed. The efficiency of the steam-heatedcylinder C is materially enhanced by the heads h 7i', closing the endsof the cylinder and confining the heat in the cylinder during theoperation of shaping the blanks'.

Vhat I claim as my invention isconnected by rods d d and metallic pipesfj" receiving said rods through them and abutting against the cradlessubstantially as set forth and shown.

3. The combination, with the cylinder C,

die g and press-screw I, of the head it formed l with the recess r', thedie g' seated in said recess and the bolt u securing said die to theaforesaid head as set forth and shown.

et. The combination of the cylinder C formed with the steam jacket D andopening D through said. jacket, the door B over said opening, the heads7L 7i closing the ends of the cylinder, the rack R seated in thecylinder for supporting the blanks, the die g' fastened to one of saidheads, the press-screw I extending through the opposite head, and thedie g pivotally connected to said screw as set forth. f

5. The combination of the cylinder C formed with the steamdjacket D, theheads 7i 7L closing the ends of the cylinder the tie-rods z' 'L' securing said heads tothe cylinder and extending beyond the head 71., thecross-heads N N secured to the extensions of said rods, the press screwI passing through said cross-heads, the nut O confined between thecross-heads and formed with the gear-wheel O, the shaft Z parallel withthe said screw and provided with the driving-pulley n, the pinion Pfixed to said shaft and meshing with the aforesaid gear-wheel, the die gconnected to the inner end of the screw, and the die g seated in theopposite end of the cylinder substantially as set forth and shown.

In testimony whereof I have hereunto signed my name this 19th day ofMarch, 1895.
